돌출부(23)는, 실린더(12)의 외주가 감합(嵌合)되는 감합부를 구비한다. 외통(14) 내에 실린더(12)와 폐색 부재(51)를 조립했을 때에, 접촉부(31)로부터 외통(14)의 일단측 단부(111)까지의 길이(h3)는, 실린더(12)의 타단측 단부(102)로부터 폐색 부재(51)의 외주측의 일단측 단부(73)까지의 길이(h2)보다 길다. 돌출부(23)의 일단측 단부면(23a)으로부터 접촉부(31)까지의 사이의 길이(h1)는, 바닥부(22)의 접촉부(31)로부터 외통(14)의 일단측 단부(111)까지의 길이(h3)와 실린더(12)의 타단측 단부(102)로부터 폐색 부재(51)의 외주측의 일단측 단부(73)까지의 길이(h2)의 차보다 크다. A protruding portion includes a fitting portion to which an outer periphery of a cylinder is fitted. When the cylinder and a closing member are assembled into an outer cylinder, a length from a contact portion to one end side end portion of the outer cylinder is longer than a length from the other end side end portion of the cylinder to one end side end portion on an outer peripheral side of the closing member. A length from one end side end surface of the protruding portion to the contact portion is longer than a difference between the length from the contact portion of a bottom portion to one end side end portion of the outer cylinder and the length from the other end side end portion of the cylinder to one end side end portion on the outer peripheral side of the closing member.
